Does Mobile Optmization really helps SEO??

Mobile friendly sites are tend to rank higher then non mobile friendly sites that's true. But it also depends on some factors such as that in which platform your maximum visitors reside and also the type of your site. For example, if your site is a shopping site then it must have a mobile version but if its is only a small blog or your site contains such elements which are only meant for desktop users then mobile version is not needed. You will rank high anyway.
